Abstract

Un système de diffusion et de réception d'un signal de balise comprend un émetteur de balise (310, 400) et un récepteur de balise (320, 500). L'émetteur de balise comprend un générateur de signal de balise (410) pour générer un signal de balise, et un système d'antenne directionnelle (420) pour transmettre sélectivement le signal de balise dans une direction correspondante parmi M différentes directions pendant chacun des M intervalles de balise (342) pendant une période de balise (340) dans chacune d'une pluralité de supertrames (330). Le récepteur de balise comprend un détecteur de signal de balise (510) pour recevoir et détecter le signal de balise, et un système d'antenne directionnelle (520) ayant un diagramme d'antenne comprenant un lobe principal et étant apte à orienter de manière sélective le lobe principal dans une direction sélectionnée parmi N différentes directions pendant chacune d'une pluralité de trames de récepteur ayant chacune une période de temps sensiblement égale à une période de temps de l'une des supertrames.
